    Sammanfattning : In the human body, the main function of the healthy thyroid gland is the regulation of the metabolism and hormone production. Included in the thyroid are organized structured and uniformly shaped follicles ranging from 50-500 μm in diameter. LÄS MER

  4. 3. ENVISAT ASAR for Land Cover Mappingand Change Detection

    Master-uppsats, KTH/Geodesi och satellitpositionering

    Författare :Kazi Iashtiak Ahmed; [2006]
    Nyckelord :;

    Sammanfattning : The principal objective of this research is to investigate the capability of multi-temporal,multi-incidence angle, dual polarization ENVISAT ASAR imagery for extractinglanduse/land cover information in the rural-urban fringe of the Greater Toronto Area (GTA)using different image processing techniques and classification algorithms. An attempt todetermine the temporal change of landuse is also made. LÄS MER
